For 170gr. and under, I stick w/ RL22.
For 180, up to 190, IMR7828 seems to work well.
150gr. MK
RL22..75gr.
210M primers, start about 2 gr. below 75gr.

170gr. MK
IMR7828...79.5gr.
210M primers
Win brass
Always start lower, but these are really good loads, for a very fickle Sako 75 300WM.

That 150gr. MK, is simply lethal in my rifle, w/ RL22.

Hope this helps...sakofan..

My WinM70 in 300WinMag likes the 190SMK with 76grs of H1000 lit by a WLRM primer or 77grs with the F215. Shoots sub moa to 600yds, haven't shot it any farther. Velocity is around 2975fps with 25.5" barrel.

I will ditto S1's suggestion of H-1000 as a best powder for the .300 Win. and also suggest H-4350. I burn a lot less H-4350 (10 grains) in my .300 with super results.

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
